I have to agree with what the guy said about how a 300 mile range (and, I might add, a 5 minute recharge time) seems to leave no reason to develop hydrogen vehicles. Batteries just have so many advantages:

1. Absolutely no emissions from your vehicle. (Power plants are another issue, but creating hydrogen in the first place isn't clean either.)
2. More efficient - at this time, it seems to take much less energy to create electricity directly than it does to create hydrogen.
3. We already have an electrical infrastructure. It goes to everyones home and every gas station already. There's no "rebuilding gas stations for hydrogen at all.

So the question is - what advantage would hydrogen have at all?
